  Could be puged somewere. do you get heat inside from the heater?  Water pump might be bad.  When it gets warm check the hoses. There are two going to the fire wall about 1 inch round, these are the heater hoses. One should be hotter than the other.  Also check the radiator hose on top it should have presure in it. If not the cap might be bad.

  Just a couple of thoughts, hope this helps.    :arcadefreak:

Replace the rad cap and see what happen. Usually this simple part is neglected and usual cause of overheating.

Another reason could be a faulty waterpump or air bubbles in the lines that could cause the overheating Did you check/replaced the thermostat?
